FAQ of geosynthetics :

What is geosynthetics ?

Geosynthetics form a perfect erosion control fabric used extremely widely in civil engineering to stabilize and reinforce slopes and soil under or next to roads, railways, dams, water reservoirs etc.. They can be easily applied which minimizes the time of construction, as well as they limit the resources and materials necessary.

Made of steel-plastic straps with arabesquitic on the surface , it can bear high tensile strength .This material has considerable tensile strength in longitudinal and lateral directions. This chain structure can effectively bear and diffuse forces on soil and is applicable to large area permanent load bearing foundation as a reinforce.

Make reinforce treatment for various of soft soil foundation to evenly distribute load stress and reduce unevensettlement , it is easy to wash coal . used in highway ,railway,port,airport, municipacl and projects of supporting in the recovery working face of coal mined and ladeway in the coal mine .

Q:How to restore the plastic geogrid after being destroyed?

3 when laying geosynthetics, the direction of high strength should be placed in the main stress direction of the embankment.4 geosynthetic materials should be paved after the design requirements of the back section, and timely coverage with sand.

Q:Geogrid tensile strength of 13.5kN/m, the unit should be how to understand?

Plastic mesh grille in custom-made case, first calculate the root number and the wire is thick, in the calculation of mesh size for tensile impact, your problem is that the tensile strength of steel grating is the tensile strength of each of the above. There are problems can be private chat, hope to adopt Thank you

Q:Geogrid construction must be folded back 2m wrapped in compacted packing on it?

Edit this section of geogrid construction notesPaved geogrid should be smooth, paving layer after acceptance, to prevent longitudinal askew phenomenon, according to the width of paving layer or draw white thread, you can start paving, and then use the end of the nail fixed grid (nail 8, per meter wide uniform fixed distance) well, after the end of the fixed grid, with the paving machine will grill slowly pulled forward each shop, shop 10 meters long artificial tightening and straightening once, until a volume grating puwan, put the next volume, operation with a roll of puwan with roller 6T-10T from the starting point to begin the direction of rolling over, (steel rolling as road paving in the surface layer and the leveling layer, the machine is appropriate; such as grid laid directly on the concrete pavement, with the roller roller is appropriate) ground shop: Volume long unit as the laying of the long, the grid should be covered the long shop Full, then the overall check a paving quality, and then paving the next section, the next section of paving, grille and grille can be used lap length 10-15CM, and fixed with nails or wedge to shop in second, to the direction followed by analogy with operating requirements.

Q:What is the single geogrid 60kN/m

Unidirectional geogrid, the tensile strength is not less than 60 kn per meter

Q:What is high strength geogrid

Like fiberglass 150KN polyester 180KN unidirectional plastic 200KN

Q:What is the vertical spacing of Geogrid

Geogrid generally by horizontal and vertical staggered from the simple meaning of space can also be understood that the size of the lattice gap.

Q:What is the difference between unidirectional geogrid and two-way geogrid

By stretching, the chain shaped molecules which are scattered in the original distribution are in a linear state, which improves the tensile strength and rigidity of the grid. In the soil, through the grid mesh and soil between the occlusion and interlock,

Q:What kind of products are the high strength and high strength micro - pile geocell?

The welding department adopts the unique welding technology, welding the two reinforcing ribs together, the welding surface of the node is large, and has high peel strength, shear strength and tensile strength.

Q:What is the meaning of the highway geogrid gsl50/hdpe

150 refers to the tensile strength is 150KN, it is impossible to two-way tensile plastic geogrid, plastic composite geogrid material is HDPE material,

Q:Where is the geogrid used?

1 strengthen the embankment, can effectively spread the load distribution to improve the bearing capacity of subgrade stability and prolong the service life; 2 can bear larger alternating load; 3 to prevent the loss of crack and deformation, caused by subgrade materials; 4 to fill the retaining wall after the self bearing capacity increase, reducing soil pressure, less retaining wall to save costs, prolong the service life and reduce maintenance costs; 5 with spraying anchor concrete construction method for slope maintenance, not only can save 30% to 50% of the investment, but also can shorten the period of more than 6; in the highway subgrade and surface layer and soil geogrid, can reduce the deflection, reduce rutting, delayed crack the emergence time of 3 - 9 times, can reduce the thickness of the layer structure of 36%; 7 is applicable to all kinds of soil, no place to be drawn, saving time and labor; 8 the construction of simple and quick, can greatly reduce the construction cost.
